Ecosystem services (ESs) in rapidly urbanizing agricultural basins are vulnerable to environmental changes. Adequately understanding the driving forces and the dynamics of ESs related to water quantity and quality can provide a basis for making sound management decisions on the development of basins. Here, we explored the impacts of future land use and climate changes on four ESs: nitrogen and phosphorous purification, water supply, and soil retention services in the Taihu Basin region of eastern China. Spatially explicit methods, a cellular automata-Markov (CA-Markov) model and the delta downscaling method were used to quantify the ESs, simulate land use changes, and project future climate changes, respectively. We built a business-as-usual land use scenario, representative concentration pathways (RCPs) scenarios for climate change, as well as a combined land use and climate change scenario to analyze the changes in the drivers and the responses of ESs. The results showed the following: (1) future land use changes would significantly enhance the nitrogen purification service while reducing the phosphorus purification service compared to other services; (2) climate change would have substantial effects on water supply and soil retention, but these impacts would vary with different RCPs scenarios during three future periods; and (3) the combined scenarios of both drivers would obviously influence all ESs and lead to a nitrogen purification service that was different from the other three services. Moreover, the policy implications of the results were discussed. The findings can help guide the creation of policies for land structure and patterns, climate change adaptation, and ecosystem-based management to promote the sustainable development of watersheds at the regional scale.

Vegetation restoration is widely used to reduce soil erosion and control soil degradation, which is conducive to improving soil quality. Aerial seeding is an effective vegetation recovery method that has been applied in large areas with severe soil erosion in China. Pinus massoniana is not only a typical native coniferous tree species, but also a pioneer tree species for vegetation recovery in subtropical China. This study evaluates the soil quality of aerially seeded P. massoniana plantations of different stand ages and examines the vegetation factors affecting soil quality. Principal component analysis and Pearson correlation analysis were used to determine the minimum data set (MDS) for developing a soil quality index. The relationship between soil quality and vegetation factors was analyzed using redundancy analysis. The MDS was established with soil bulk density, field water capacity, non-capillary porosity, total nitrogen, soil organic matter, and pH. The results showed that the soil quality significantly increased with vegetation recovery age at 0–20 and 20–50 cm soil depths. The soil quality of the surface layer was mainly affected by understory vegetation and litter, whereas that of the deep layer was mainly affected by trees. Therefore, the appropriate management of P. massoniana forest, achieved by appropriately extending forest management rotation, replanting broad-leaved trees, and minimizing the damage to understory vegetation and litter, is essential for effectively improving soil quality.
